someone solvw this for me please

The velocity of the mass at time, t = 1 s, is determined as 20 m/s.
The magnitude of the force experienced by the body is calculated as follows;
|F| = √(8² + 6²)
|F| = 10 N
From Newton's second law of motion;
F = ma
where;
a = F/m
a = 10 /0.5
a = 20 m/s²
v = at
v = 20 x 1
v = 20 m/s
